(adsbygoogle = window.adsbygoogle || []).push({}); I hav a psp 2001, that blue one that came with the madden package. It has a ofw of 6.20. Could I still downgrade it to a firmware where I could put a cfw on it? like 5.00m33? like could I use a pandora battery and mms to do it?

Yes, you can just check the motherboard.

check it? for what?

some of the 2001 series as a unhackable motherboard.

karma is right

Most 2001 series are unhackable and yours is one of them I believe. Im lucky to still have my hackable one. =)

i wish i knew this before i f`ked over mine. when i turn it on only the green light comes on
